>Cancer incidence is flat to slightly decreased since then
This is a nonsensical point because it can trivially both be true that cancer rates fall overall while CT scans cause additional cases of cancer. The comparison has to be, and that's what the original paper did, how many additional cases of cancer do you get from radiation in particular, that is to say cancer incidence could obviously be even lower all other things being equal.
